You want to compare the numbers of hours spent on recreation each week by teachers and non-teachers in your state. You take 100 random samples of 15 teachers and 100 random samples of 15 non-teachers throughout the state and record the median value of each sample. The double box-and-whisker plot shows the distributions of sample medians. Are the samples likely to be representative of all teachers and non-teachers in your state?

Answer:

slope of line: 4/3

Step-by-step explanation:

The probability that Gavin will select two red tiles when he randomly draws one tile from each bag is 1/18. So, option C is the correct answer.

The probability of an event is a fractional value determining how likely an event is to occur. The formula of the probability of an event =

The number of favorable outcomes to an event/total number of outcomes in that event.

Two events A and B are said to be independent when the occurrence is not related to the occurrence of the other.

The probability of independent events is given by:

Probability(both A and B occurs) = Probability(A occurs)*Probability(B occurs)

We are informed that Gavin has two bags of tiles, and he draws one tile from each bag.

We are asked to find the probability that he will select two red tiles.

Let the event of drawing a red tile from bag 1 be A and bag 2 be B.

Since the two bags are different, A and B are independent events.

Now, the number of red tiles in bag 1 = 3. These are in favor of A.

The total number of tiles in bag 1 = 18.

∴ Probability(A) = 3/18

or, P(A) = 1/6.

Now, the number of red tiles in bag 2 = 3. These are in favor of B.

The total number of tiles in bag 2 = 9.

∴ Probability(B) = 3/9

or, P(B) = 1/3.

Since A and B are independent, the occurrence of A and B together is,

Probability (A and B) = P(A)*P(B)

or, P(A and B) = 1/6 * 1/3 = 1/18.

∴ The probability that Gavin will select two red tiles is 1/18.

Hence, option C. is the correct option.

Answer:

Length- 6 centimeters.  Width- 5 centimeters

Step-by-step explanation:

Ok, so 1/2 centimeter = 6 inches

let’s first take the length witch is 72 inches and divide that by 6. Then, since it half a centimeter, divide in half.

72/6 = 12     12/2 = 6 centimeters

Next is the width. Now we the same thing as the length. Take 60 and divide by 6 then divide in half.

69/6 = 10.    10/2 = 5 centimeters

In summary, The scale drawing has length of  6 centimeters and a width of 5 centimeters.

Step-by-step explanation:

Japan 80.09 = 16.018

Switzerland 75.81 = 15.162

Answer:

In Japan, the average ticket costs $17.73.

In Switzerland, the average ticket costs $13.45

Step-by-step explanation:

80.09-75.81=3j+2s-(2j+3s)

4.28=j-s

So a ticket from Japan costs $4.28 more than a ticket from Switzerland. so we can write the equation:

3s+2(s+4.28)=75.81

5s=67.25

s=13.45, j=13.45+4.28=17.73

Step-by-step explanation:

hope this helps if it is wrong please let me know

Answer:

Step-by-step explanation:

First, you have to simplify and solve for x.

x + 2x + 6 < 50

3x + 6 < 50

3x < 44

x < 14 2/3

x has to be smaller than 14 2/3. The only two numbers in the set that works are {13, 14} replace x with both numbers and solve

14 + (28) + 6 = 50

13 + (26) + 6 < 50

the correct answer is 13

Answer:

The equation relating the number of cars to the number of passengers is p = 4n

Step-by-step explanation:

Given that certain type of car has room for 4 passengers

To find: write an equation relating the number of cars to the number of passengers

Let "n" be the number of cars

Let "p" be the number of passengers

From given information,

Car has room for 4 passengers. Therefore, we can frame,

number of passengers = 4 ( number of cars )

p = 4 (n)

p = 4n

Thus the equation relating the number of cars to the number of passengers is p = 4n
